PAPER-ROLL HOLDER.

. Application filedApril 3,

To aZZ whom it may concern:

Be it known that I, LAWRENCE B. (inasnrncnn, a citizen of the United States, residing at the city of Richmond, in the State of Virginia, have invented certain new and useful Improvements in Papcrdloll l folders, of which the following is a specification.

This invention relates to holders used in stores for supporting rolls of wrapping paper so that they can be revolved; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed which permit the roll to be revolved with facility, and to have the papers torn or separated from it in sheets of any desired length.

In the drawings, Figure 1. is an end View of a roll holder constructed according to this invention. F 2 is a front view; and Fig. 3 is a plan view, of the same. Figs. 4 and 5 are respectively a side view and a plan view of one of the arms which support the blade, drawn to a larger scale. Fig. 6 is a cross-section through the arm, taken on the line 6-6 in Fig. 4:.

The roll of paper 7 is supported by a frame having a main portion 8 formed of a single metal bar bent to form three sides of an oblong figure. The bottom of this part 8 has inwardly projecting feet 9 which are an ranged. parallel to its top member 10 which extends crosswise between its side portions. Foot bars 12 are arranged crosswise of the frame and are secured at their middle parts to the upper sides of the feet 9, and have cushions 1 1 of india rubber secured to their end portions, and adapted to support the frame on a store counter. A crossbar 15 is secured between the two feet 9, and 16 are the rivets which secure the crossbar and the foot bars to the feet. A frame constructed in this way is light and rigid, and is very in expensive to manufacture in large quantities.

U-shaped bearing brackets 17 are secured to the sides of the frame, and the center shaft 18 of the roll is journaled in suitable antifriction bearings 19 supported in these brackets.

A blade 20 is provided for separating the papers into sheets, and is pivoted to the top member 10 of the frame by forked brackets 21, arms 22, and pins 2 1, the said brackets bein g secured to the underside of the top memher and projecting downwardly. The blade rests against the periphery of the roll parallel to its axis, and it is very desirable that its 1922. Serial No. 549,088.

end portions should bear with equal pressure on the roll, which is often not truly cylindrical, otherwise a sheet torn hastily from the roll will have a ragged edge, and will often not tear off in a straight line.

In order to permit the blade to twist to suit the roll, the arms 22 are formed of spring sheet metal, and their main parts are bent around to tubular or channel-shaped form. These arms have flat ends 25 which are secured to the blade, and eyes 26 for engaging with the pivot pins. The arms are stiff and strong, but their ends 25 twist freely on the axes of the bars and with relation to the eyes 261 The blade may have one or more corrugations 27, if desired, so that its end portions may twist freely with relation to each other, and so that the blade will otherwise be stifi? and strong.

The blade is pressed against the roll by two helical springs 30 secured at one end to pins 31 which project laterally from the. arms 22, and at the other end to pins 32 on the side portions of the frame above the level of the pivot pins 24. The springs norin ally extend diagonally of the side portions of the frame, and project below the pivot pins 24. l/Vhen the blade is raised, as shown in dotted lines in Fig. 1, to insert a new roll of paper, the springs bear against the edge of the top member and are bent, and the springs then sustain the blade and the arms in the raised position.

The main portion 8 of the frame can be a plain flat bar in crosssection, as shown, and for large and long rolls it can have any approved flanges or corrugations which will strengthen and stiffen it;

What I claim is:

1. In a roll holder, a supporting frame for the roll, brackets depending from the top member of the frame between its sides, arms pivoted to the said brackets, a blade secured to the said arms and adapted to bear on the roll, and helical springs arranged between the said arms and the sides of the frame and secured to the said sides above the pivots of the arms and to the arms below their pivots, said springs normally operating to press the blade downwardly on the roll and being bent by contact with the top member of the frame when the blade is raised pivotally to a point above the level of the top member so that they support the blade in its raised position. 2. In a roll holder, a supporting frame for the roll, arms formed of spring sheet metal and pivoted to the frame at one end, and a blade having its end portions secured to the other ends of the arms, the said blade having a longitudinal rib which prevents it from bending and permits it to twist, and the main portions of the said arms being incomplete tubes in cross-section so that they do not bend but are free to twist, thereby permitting the said blade to bear uniformly at all parts of its edge uponan unsymmetrical roll.

3. In a roll holder, a supporting frame for the roll, arms pivoted to the frame and formed of spring metal with their main parts hent around. their axes to form torsion springs so that their ends can twist relatively toeach other, and a blade secured to the arms and adapted to bear on the roll, said spring arms operating to permit the end portions of the blade to twist to suit the irregular surface of the roll.

4. In a roll holder, a supporting frame for the roll, arms pivoted to the frame and formed of sheet spring metal, said arms having eyesat one end and flat end portions at the other end and having intermediate portions of incomplete tubular form which form torsion springs and permit their flat end portions to twist relatively to the said eyes, and a blade secured to the said flat end portions and adapted to bear on the roll.

In testimony whereof I have aflixed my signature.
